3 Claims. (01. 238-493) This invention relates to improvements in railis molded about the wire encased core into the road equipment and pertains particularly to an improved form of tie.

The primary object of the present invention is to provide a new and novel type of railway tie which can be economically produced and which will result in the saving of the large amount of timber which is now employed in the making of ties.

Another object of the invention is to provide an improved railway tie which will materially outlast ties made of wood.

Still another object of the invention is to provide a railway tie which is built up upon a core of compressed straw, the core being reinforced by mesh wire and cement, the body thus produced having a top plate of wood and metal to which the railway rails are secured.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 1 is a View in top plan of a tie constructed in accordance with the present invention, a portion at one end being removed while at the other end a rail is shown secured thereacross.

Figure 2 is a view in side elevation of the tie showing the attached or mounted rails in cross section, a part of the body of the tie being broken away.

Figure 3 is a sectional View taken upon the line 33 of Figure 1.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the views, the numeral l indicates the core of the present improved tie which is composed of straw, preferably wheat straw, which is highly compressed into the desired form. This compressed straw core is then enveloped in the wire mesh 2 which is of relatively heavy construction to serve the double function of maintaining the compressed straw core in shape and provide a means for binding to the core the enveloping cement outer body 3 in which the core is enclosed. The cement outer covering 3 of the tie is made relatively thick, as illustrated in Figure 3, and

desired tie shape. At each end of the tie there is secured therein to a bolt 4 which projects from the side of the tie which forms the top when the tie is placed in use. Disposed over the top side of the tie from which the bolts 4 project is a plank 5 of wood which is provided with suitable apertures at its ends for the passage of the bolts 4 therethrough and this wood plank 5 then has placed thereover the metal plate 6 which, like the plank 5, extends the length of the tie and has end apertures for the extension of the bolts 4 therethrough, the plate 6 and plank 5 being then secured down to the main part of the tie body by nuts 1 applied to the bolts 4.

In order to prevent to a certain extent the entrance of moisture between the plank 5 and plate 6 and between the plank 5 and the top of the cement portion of the tie, the plate 6 has the downwardly extending flanges B at its side and end edges which extend across the plank 5, and overlie a portion of the cemented surface of the tie as illustrated in Figures 2 and 3.

Riveted or otherwise suitably secured to the metal plate 6 adjacent each end is a rail bed plate 9 upon which the track rails ID are mounted when the tie is put into use. Each of these bed plates 9 has at its inner side the reversely bent rigid flange II beneath which a side flange of a rail I0 is adapted to engage, as illustrated in Figure 2. Adjacent its opposite end each base plate is laterally extended to form the wings 12 which project beyond the sides of the underlying tie, as illustrated, and this outer edge is provided with the transverse upturned flange I3.

Each of the wing portions I2 of the bed plate has a bolt aperture I4 therethrough for the purpose hereinafter described.

Associated with each rail supporting bed plate 9 is an elongated clamping plate [5 which has an oifset edge portion l6 which is adapted to position over the other flange of the rail upon the bed plate, the portion [5 of the clamping plate resting upon the bed plate 9 and extending over the wing portions l2 thereof.

Each clamping plate is provided with suitable apertures adjacent its ends for the reception of bolts I! which pass through the apertures l4 of the lateral portions of the bed plates, so as to secure the clamping plates in operative position.

While the bed plates 9 have been shown as having the lateral wings integral therewith, it is to be understood that the invention is not to be limited to this specific construction as it will be obvious that a separate plate member may be disposed transversely of the tie to be riveted to the plate 6 or extend beneath the bed plate 9 as found convenient.

From the foregoing it will be readily apparent that a tie constructed in accordance with the present invention may be economically produced and will securely hold a track rail inoperative position. It will also be apparent that the construction of railway ties in accordance with the present invention will result in a material saving in timber so that the same may be put to other and more desirable uses.

What is claimed is:

1. A railway tie, comprising a compressed core of fibrous material, a fabricated binder surrounding and directly contacting said core, and having open meshes, a plastic material in'contact with and enveloping thebinder and filling, said meshes and held in contact with the core by the binder, and means secured to the body composed of the binder, core and enveloping material for securing a track rail thereto.

2. A railway tie, comprising a main body consisting of a core of compressed fibrous material, a fabricated metallic reinforcing material surrounding and directly contacting the core, a molded plastic encasing the core and reinforcing and entering into the meshes of said fabricated material and contacting the core, rail supporting plates secured to the body, and means cooperating with said plates for clamping the rails to the plates.

3. A railway tie, comprising a main body portion consisting of a core of compressed straw, a binder of wire fabric about and in direct contact with the core, a cement covering enclosing the core and binder and held in contact with and about the core by the binder through the meshes of which the cement extends, a plank of wood overlying one surface of the body, a metallic plate covering the top and edge surfaces of said plank and the joint between the plank and cement, means securing the plate and plank to the body,

and means for seeming railway track rails to said
